ROBERT ENGLISH, OF AUSTIN, TEXAS.

GRAIN-HEATER.

SPECIFICATION forming part of Letters Patent No. 265,664, dated October10, 1882.

Application filed June 12, 1882. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT ENGLISH, of Austin, Texas, have invented anew and useful Improvement in Grain-Heaters, of which the following is aclear, full, and exact description, reference being had to theaccompanying drawing, making a part of this specification, in which thefigure is an elevation, partially in section, of; my improvedgrain-heater.

My invention relates to that class of heaters designed for heating grainand drying it prior to its being subjected to the grinding process; andit consists of acombination of devices hereinafter explained andclaimed.

To enable others skilled in the art to make and use my invention, I willproceed to describe the exact manner in which I have carried it out.

In the drawing,A represents the boxing in which the grinding-stonesrevolve, and B is a hopper over the same. Within this hopper I place theinverted-funMel-shaped mouth 0, attached to the hot-air pipe 1), leadingfrom the furnace E, which furnace is provided with a blast-fan, F, inorder that the hot air may be applied under pressure to the wheat orother grain as it enters the hopper B. The lower or under portion of themouth G is entirely open to allow a free passage of the hot air, and, asit is of a diameter little less than the hopper itself, the hot airstrikes through the grain as it is shed from the upper incline to thelower part of the hopper on its way to the grindingstones, and dries it.To assist in the process of drying, I perforate the sides of theinverted-funnel-shaped mouth 0, so as to allow the heated air to strikethe layer of grain as it slides down the inclined sides of the month.

On the inside of the hopper B, and above the funnel-shaped mouth (3, Isecure the centrally-inclined flange b, for the purpose of conductingthe grain toward the center of the hopper and discharging it as much aspossible on thehighest point of the mouth 0, so as to increase its lineof travel over the inclined surface of the mouth, and thus perfect thedrying of the grain before it reaches the grindingstones. Beneath theflange b, I make the perforations 1) around the hopper for the escape ofthe heat after it has passed through the grain.

It is evident that by the construction I have described a most effectiveand simple heater is secured, one that cannot get out of order, and notrequiring skilled labor to operate it.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

and perforations b, in combination with the hot-air pipe D, providedwith the inverted-funnel-shaped mouth (J, having its sides perforated,and all constructed and arranged to operate substantially as and for thepurpose de scribed.
